3.3.2
Drainage of the antenna
A simple drainage mechanism is used in the bottom of the unit to provide venting
and drainage of any condensation inside the radome. Correct function of the
drainage system will only be ensured by following criteria mentioned in S
ection
3.3.3
Cleaning
The antenna can be cleaned and washed together with the vehicle (hosing down or
driving through a washing tunnel). When using a pressure washer, do not direct the
jet towards the antenna from short distance. Avoid pressure washing at maximum
pressure; the sealing gasket may not withstand such high-pressure jet.
Never direct a water jet towards the drainage holes at the radome bottom. Water
may be forced up the drainage channel.

Magnetic mounting (optional)
Three magnetic mounts (P/N: 3501152-0002) are optional for the terminal
installation.

The magnetic mount consists of three high-intensity magnets with rubber coating.
First put the bolt through the magnet. The hole in the magnet has a recess on one
side - ensure the bolt head fits into this recess in the magnet. Next, place two
rubber washers on each bolt.
Put the bolt through the hole on one of the antenna’s
three “ears”
.
Then place two rubber washers on each bolt above each “ear”, the
stainless-steel washer above the upper washer and the M5 protective nut on top.
Torque until height is 37mm / 1.46”, as shown
Now place the antenna with magnets on the roof of the vehicle.
When installing the antenna cable, it is important to protect it against moisture
–
using self-amalgamating tape wrapped around the coaxial connector. Also, be
careful with the cable run from the antenna and secure it at short intervals. An
unsupported length of cable will vibrate when driving and could over time develop a
bad connection.
Dismounting
:
Grab the antenna near one of the magnets and lift up. When one magnet is loose,
the other two are easy to “pop off”.
